Mr Murdoch has publicly questioned how the multi-billion-dollar policy would be paid for, and the News Corp-owned Daily Telegraph paper has taken an anti-Labor stance as politicians hit the campaign trail.

Speaking on the ABC's 7.30 program last night, Mr Rudd again questioned whether commercial interests are driving Mr Murdoch's opposition to the broadband project.

"I'm actually worried about Kevin Rudd's state of mind. He seems to be descending into some dark world of conspiracies where everybody's against him and it's led by Rupert Murdoch," she told Lateline.

"He's spent the last three years leaking against his colleagues, getting stories in News Corporation papers and now that the News Corporation editorial doesn't think that he's fit to be Prime Minister, a view that his colleagues share, all of a sudden it's a conspiracy.

"And then he's got this theory that somehow Malcolm Turnbull launching our broadband policy at Fox Studios was something sinister. I mean, seriously? It's a showcase for high technology. It would have looked good on TV. Why wouldn't you launch your broadband policy there?

"For Kevin to find something sinister in that, I think he's lost the plot."

"Albo's explanation for German beers with Thomson: I know nuthink!" the paper said.

The paper has previously called on voters to "kick this mob out" on September 7, and declared "it's a ruddy mess" following the release of Labor's economic statement.

'Their agenda is clear'

Mr Albanese says the Daily Telegraph's agenda is there for all Australians to see.

"I think people will look at the agenda they are running, and frankly be pretty offended that they are being told what to think and how to vote by a newspaper," he told ABC Local Radio in Newcastle this morning.

"With the Daily Telegraph, there will be a different headline and a different front page every day, but their agenda is clear."

News Corporation has previously denied its newspapers are influenced by Foxtel's interests.

"Any suggestion that the editorial position of our newspapers is based upon the commercial interests of Foxtel demonstrates a complete ignorance of both our business and of Foxtel," it said in a statement on Wednesday.

Meanwhile politicians across the country are gearing up for day four of the election campaign, which is expected to again be dominated by the economy.
